What does “You’ve proved your point” mean?
I’d hazard a guess that it’s relatively self-explanatory, as in: ok, we see that you can do it, so please stop now.
I don’t know. Could be wiki leaks knew someone was trying to make a point. Apparently earlier O’Keefe’s Twitter account was to be shut down for violating some rule, the message he got said he was suspended from tweeting for 11 hours. Or not. I didn’t ask wiki leaks what they meant by it. Their words, not mine.
